A'UTOXSEILE BRAKE HECEMIISM.

pplication lcd January 16, '19%. i Serial No. 81,795.

My present invention-has to do with brake meehanisms of automobiles;and'it contemplates the provision of a lbrake mechanism in which bymeans under the control of the driver of an automobile the'rotetion ofthe propeller shaft is utilized to powerfully apply the brakes, and thiswith but little eiort on the part of the driver. l

@ther objects and practical advantages ot the invention will be fullyunderstood from this* following description and claims When the same arereed in connection With the' drawings, accompanying end forming part ofthis specification, in which:-'

15 Figure l is e view diagrammatic in cherscter and partly in plan andpartly in sec tion`illustrating the preferred embodiment o1' my'invention.

Figure 2 is e view partly in, elevation and partly in section taltenatright4 angles to Fiume 1. I

imilar numerals' oi" reference designate corresponding parts in ell ofthe views of the drawings. l y

1 show in the drawings a propeller shaft 1 extending :from atransmission casing 2, and it will be understood that a female dy Wheel3 is xed to and arranged to, rotate with the shaft l. Opposed to the SyWheel 3 the inner portion of which is tapered as designated by e, is acomplementary, tapered, male clutch member 5. The clutch member 5 isrdtatable with a sleeve 6 having a cir cumerentially grooved portion 47,and the 'said sleeve 6 is mounted on a tubular ro jeotion 8, having atone end a flange 9 ed i tothe casing 2 and also having'at its oppositeand rear end a flange 10 between which and the clutch member 5 isinterposed an expansion spring 11, the said spring* 11 tending, ofcourse, to move the clutch member 5 forwardly or away from the ily Wheel3. A rock, shaft 12 is appropriately mounted above the sleeve 6, Figure2, and said shaft 12 is provided with a yoke 13 engaginff thecircumferentially grooved portion ofbthe sleeve-6 and is also providedwith a crank 14. This latter is connected through a rod 15 With a pedallever 16 subject to the action of a retractile spring 17. Thus when thepedal lever 16 is moved forwardly 'through the medium of the foot of theautomobile driver, the clutch member-5 will 'be thrust against theaction of thespring 11 into rictional engagement with the y 'ed throughrods'22 with the outwardly wheels of the automobi e,

'when the clutch member 5 is disengaged Wheel 8, and will be turned withand by the said fly rvheel 3. lfVhen, however, "the pedal lever 16 1srelieved of pressure the expan- Appr-o riately mounted at 18 aretransyerse bra e shafts 19 provided with pendent cranks 20 and alsoprovided with an edditional crunlrQl. The cranks 21 are connect dirooted arm of bell cranks 23, and the inner arms of the said bellVcranks 23 are crninectedA through rods 24 with the clutch member 5.

Thus when the Said clutch member 5 is turned through the medium of the ywheel 3 as before described, the bell cranks 23 will be rocked es willalso the brake shafts 19, whereupon the brake shafts pulling on cablesor other appropriate connections 25 75 Will apply the brake pro )er ofthe four which brake proper may be of conventional construction or ofany construction consonentvvith the purpose of my invention. l Y 8o'`When deemed enpedientgetractile springs 3() are connected to lthe innerarms ofthe bell cranks 23 and to the freine-of the automobileso as toassist in releasing the brake from the ily wheel member 3 Yas beforedescribed. l

Manifestly the element Erv'vill operate as a dy wheel only when theautomobile is running, and it will be understood that the faster thecaris propelled the'more eiective will be the action of my novelbrakemechanism when the seme is put into use.4 Again it will beunderstood that but little @o-rt on the part of the driver is necessarylo the o eration of `m novel brake meehaniem, t ie movement o the pedal,lever 16 servin merely to engage the'clutch member 5 `vit the ily Wheel3, and the rotation of the said fly Wheel 3 bein utilized for theforcible 190 and prompt applic tioiqf the brake.

Notwithstan ingthei practical advnntogefascribed to m novelf'.'mechanism, it

reke will be apprecifted that the said mechanism is simple and colnpiotin construotionand in 1o. general isI well opted to withstand the usageand exposure to which automobile appurtenances are ordinarily sub'ected.

l. have entered into a detailed escription A' of the constructionandrelative arrangement n@ of the parts embraced in the prent and#preferred embodiment, it? my inventionwin order to impart a fulLclearand exact understanding of the said embodiment. I do not desire,however, to be iuulcrstood as limiting myself to the preciseconstruction and arrangement of parts as disclosed, my invention being;`defined lby my alipeuded claims Within the scope of which changes inslructurey and changes in arrangement may be made Without departure frommy iuvenn tion.
